I've had a dry cough and could for over a week all the doctor gave me was robitussin dm but don't take it only once at night if I really can't sleep drink a lot of fluids and some honey halls that's helped me a lot good luck I'm 32 weeks and I feel ur pain and hope u feel better stay warm :)
Pineapple juice is really good natural remedy for a cough and I used sudafed for my cold I had. Sleep a lot and drink a lot of water!
